Diltiazem

Diltiazem

Diltiazem, a non-dihydropyridine calcium channel blocker, stands as one of the most prescribed medications. Diltiazem helps treat high blood pressure and control chest pain (angina). This medication helps patients by relaxing their blood vessels and reducing their heart's workload. 

The drug proves useful beyond these basic treatments and helps manage atrial arrhythmia, paroxysmal supraventricular tachycardia and pulmonary hypertension. While diltiazem effectively controls these serious conditions, patients should know it doesn't cure them. This article will explain what tab diltiazem is, its uses, and its side effects.

What is Diltiazem

Diltiazem is a benzothiazepine calcium channel blocker drug. The medication blocks calcium from entering heart and blood vessel cells, then makes them relax. Your blood can flow through wider pathways, which reduces your heart's workload. Patients can expect the medicine to work quickly, as immediate-release tablets start acting within 30 to 60 minutes. 

Diltiazem Uses

Your doctor might prescribe diltiazem to:

• Control high blood pressure
• Stop chest pain (angina)
• Manage rapid heart rate in atrial fibrillation
• Treat anal fissures (as cream or ointment)
• Decrease Raynaud's phenomenon symptoms

How and when to use Diltiazem Tablet

• Follow your doctor's instructions carefully while taking diltiazem. 
• You can take the medication with or without food, but stick to the same schedule each day. 
• The tablets or capsules should be swallowed whole with water—never chew them. 
• For anal fissures, use a 2.5 cm strip of diltiazem cream or ointment on the area around your anus two times a day. Make sure to follow the directions on the package or given by your doctor.
• Take a forgotten dose once you remember, unless your next dose is due soon.
• Keep the medicine in a closed container at normal room temperature. Avoid placing it near heat, moisture, or direct sunlight. 

Side Effects of Diltiazem Tablet

Common side effects include: 

• Ankle swelling
• Dryness of the throat
• Body pain
• Constipation 
• Palpitations
• Dizziness or sleepiness
• Orthostatic hypotension

Seek immediate medical help if you experience severe stomach pain, yellow skin/eyes, or unusual changes in heartbeat.

Precautions

• Diltiazem should not be taken by patients with severe heart block, extremely low blood pressure, or specific lung conditions.
• You might get dizzy or feel faint if you stand up too fast. If that happens, lie down until it stops, then sit up before trying to stand. 
• Let your doctor know about all medications you currently take.
• Inform your doctor if you have allergies to any of the drug components.

How Diltiazem Tablet Works

This benzothiazepine medication belongs to the calcium channel blocker drug class. The drug prevents calcium ions from entering cardiac muscle cells when your heart contracts.

Your blood vessels expand and create less resistance to blood flow. This natural process lowers your blood pressure. Diltiazem also reduces your heart's workload and decreases its oxygen requirements.

The medication benefits your heart in several ways:

• Decreases heart rate (negative chronotropic effect)
• Reduces heart muscle contractility (negative inotropic effect)
• Slows electrical conduction through the heart nodes

Can I Take Diltiazem with Other Medicines?

You should be careful because diltiazem affects the CYP3A4 enzyme system that breaks down many medications. The drug interacts with:

• Alprazolam
• Amlodipine
• Apixaban
• Atenolol
• Atorvastatin
• Buspirone
• Clarithromycin
• Dexamethasone
• Esmolol
• Haloperidol
• Halothane

Dosing Information

• For high blood pressure: The original dose is 180-240mg once daily, which can increase up to 480mg 
• For chest pain: Start with 30mg four times daily (tablets) or 120-180mg daily (extended-release)
• Extended-release formulations let you take one dose daily at the same time. Older patients usually start with lower doses based on their kidney function.

FAQs

1. Is Diltiazem high risk?

Diltiazem's risks mainly involve heart-related side effects. These include bradycardia (slow heartbeat), heart blocks of varying degrees, and hypotension (low blood pressure). Notwithstanding that, most patients tolerate it well with proper medical supervision. 

2. Is diltiazem an antibiotic?

No, diltiazem is not an antibiotic. This medication belongs to the calcium channel blocker drug class that relaxes blood vessels and reduces heart workload. The drug treats cardiovascular conditions, unlike antibiotics that fight infections.

3. How long does diltiazem take to work?

The medication acts quickly in your system. Blood levels become detectable within 30-60 minutes after taking an oral dose. Peak effects occur 2-4 hours after administration. Your blood pressure might take up to two weeks of consistent use to reach optimal control.

4. What happens if I miss a dose?

You should take once-daily doses within 12 hours of the scheduled time. Twice-daily regimens allow a 4-hour window. Skip the missed dose and continue your regular schedule if outside these windows. Your next dose should never be doubled to compensate for missed ones.

5. What happens if I overdose?

Diltiazem overdose can turn fatal. The symptoms include dizziness, fainting, irregular heartbeat, breathing difficulties, and confusion. Emergency medical attention becomes essential if an overdose occurs. Medical teams typically treat with gastric lavage, activated charcoal, and supportive care.

6. Who cannot take diltiazem?

The medication isn't suitable for people with:

• Sick sinus syndrome
• Certain heart blocks
• Severe hypotension
• Drug hypersensitivity
• Acute myocardial infarction with pulmonary congestion

7. When should I take diltiazem?

Your prescribed schedule determines the timing. Extended-release formulations usually need one daily dose, while regular tablets might require multiple doses throughout the day.

8. How many days to take diltiazem?

Diltiazem treats chronic conditions like hypertension and angina. Patients usually continue the medication indefinitely, sometimes for life, unless their doctor advises otherwise.

9. When to stop diltiazem?

You need to talk to your doctor before stopping diltiazem. Stopping it all of a sudden can cause your blood pressure to go up. This increases your risk of a heart attack or stroke. Patients using cream for anal fissures should continue treatment until healing is complete—usually 6-8 weeks.

10. Is it safe to take diltiazem daily?

Diltiazem works best with daily, long-term use. Patients often need it indefinitely, sometimes throughout their lives, to manage their conditions. The medication's benefits continue even when you feel better, so regular use matters.

11. What is the best time to take diltiazem?

Regular timing helps the most. Your blood levels stay stable when you take diltiazem at the same time daily. Your doctor might ask you to check your pulse each day and tell you about acceptable heart rate ranges.

12. What to avoid when taking diltiazem?

Avoid these items:

• Alcohol - side effects worsen and blood pressure drops further
• Grapefruit juice - raises Diltiazem levels in the blood
• St. John's wort - changes diltiazem's effectiveness

13. What happens when you stop taking diltiazem?

Sudden stops can trigger rebound hypertension or tachycardia. Your risk of stroke or heart attack increases as blood pressure rises. 

14. Does diltiazem make you gain weight?

Direct weight gain rarely occurs, though some fluid retention happens. This extra water weight goes away after stopping the medication. Call your doctor right away if sudden weight gain occurs—it might signal congestive heart failure.

15. Who should not take diltiazem?

People with sick sinus syndrome, certain heart blocks, severe hypotension or specific lung problems should avoid diltiazem. Doctors need to think over special cases like elderly patients, pregnant women, and nursing mothers carefully.

16. Does diltiazem affect the kidneys?

Research shows that diltiazem doesn't harm kidney function. The drug helps blood flow through the kidneys better by reducing renal vascular resistance.

17. Should I take diltiazem before or after meals?

You can take diltiazem whenever you want—with food or without. Food doesn't change how your body absorbs this medication. Just remember to take it at the same time daily to keep blood levels steady.

18. What foods should I avoid when taking diltiazem?

You should stay away from:

• Grapefruit and its juice 
• Alcohol
• Pleurisy root 

19. Does diltiazem cause weight loss?

Research hasn't found any link between diltiazem and weight loss.
